Chemiluminescence is what makes the glow worm glow, but in that case it's called bioluminescence.




Hey redewenur,

Referring to your previous post dated 14th July, chemiluminescent analyzer has been used to measure exhaled nitric oxide. Recently I have come across an excerpt from Primary Care Respiratory Journal (2009), which states that FENO was measured according to current guidelines using a NIOX MINO electrochemical analyzer or a NIOX chemiluminescence analyzer (both Aerocrine, Solna, Sweden). The latter was available at the Research Unit, 5km. from the Health Centre, but was used only when there was technical failure of the NIOX MINO. It seems that the NIOX MINO Analyzer had frequent technical failures and significant sensor inaccuracy issues causing the researcher to apply a manual correction factor and/or rely on the expensive NIOX lab instrument as a backup.

Doesn't these devices sounds cumbersome to use it? Any information about it.
